The traction control system automatical-
ly helps prevent the spinning of rear
wheels (twowheel drive models) or 4
wheels (fourwheel drive models) when
the vehicle is started or accelerated on
slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle under any speed or maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
present road conditions.

Leave the system on during the ordi-
nary driving so that it can operate
when needed.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the trac-
tion control system is in the self−check
mode, but does not indicate a malfunction. When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
rear wheels (two
−wheel drive models)
or 4 wheels (four −wheel drive models).
At this time, the slip indicator light
blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.
The brake actuator temperature increases
during continuous operation of the follow-
ing systems under conditions such as on
slippery roads.

If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no longer operate. In this
case, immediately stop your vehicle at a
safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
At the time, the slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction control system does not operate,
it is no problem to continue driving.) The
system will be automatically restored after
a short time and the slip indicator light
goes off.
With rear differential lock: However, it is
a normal operation for the light to be on
with rear differential locked. At this time,
the traction control system does not oper-
ate.

The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or operating steering wheel abrupt-
ly.
The vehicle stability control activates
when the vehicle speed is more than 15
km/h (9 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the sys-
tem is in the self
−check mode, but does
not indicate a malfunction.

The downhill assist control system is a
system that assists the deceleration of
the engine brake when you drive down
a steep hill. When you are driving down
a hill with the front drive control switch
knob in the “L4” position, push the
“DAC” switch to limit the vehicle’s ac-
celeration. If the vehicle is traveling at
a speed of 25 km/h (15 mph) or less,
you can descend at a constant speed.
CAUTION
Do not rely excessively on the down-
hill assist control system. It may not
be able to maintain a low speed over
road surfaces or offroad surfaces on
which sliding can easily occur, such
as extremely steep slopes or icy or
muddy roads.
TO ACTIVATE THE DOWNHILL ASSIST
CONTROL SYSTEM1. Turn the front drive control switch knob to the “L4” position.
The system does not operate when the
front drive control switch knob is in the
“H2” or “H4” position, or the rear differen-
tial is locked.
2. In order to make full use of the en- gine brake, putting the transmission
in “L” or “2” is recommended.
The system will operate even if the trans-
mission selector lever is in “D”, “4”, “3”
or “N”. However, when it is in “L” or “2”
the engine brake can also be utilized en-
abling the system to operate more effec-
tively.
LS17016
3. Push the “DAC” switch to turn the system on. The downhill assist con-
trol system indicator light on the in-
strument panel will come on.
If the downhill assist control system indi-
cator light flashes, one of the following
may be the cause:
The selector lever is in the “N” posi-
tion.
The front drive control switch knob is
in the “H2” or “H4” position.
The rear differential is locked.
If the indicator light does not come on
when the switch is pushed, contact your
Toyota dealer.

With the vehicle traveling at a speed of
25 km/h (15 mph) or less, release your
foot from the accelerator or brake pedal
to activate the system. The vehicle will
descend the hill at a low speed. While the
system is operating, the slip indicator light
on the instrument panel will flash and the
stop lights and high mounted stoplight will
be lit.
If you push the “DAC” switch to turn the
system off while it is in operation, the
system will stop operating gradually. The
downhill assist control system indicator
light will flash to alert the driver. To con-
tinue driving at a low speed, push the
“DAC” switch to turn the system on. The slip indicator light and downhill assist
control system indicator light come on for
a few seconds when the ignition key is
turned to “ON”. If any of the indicator
lights does not come on when the ignition
is turned on, contact your Toyota dealer.
If the system is used frequently, the
brake actuator temperature may become
too high and a buzzer will sound inter-
mittently.
If this happens, the downhill assist control
system indicator light will flash and a
buzzer will sound intermittently. When the
temperature of the brake actuator de-
creases, the system will begin to operate
again. Until it restarts, the traction control
system and hill
−start assist control system
will not operate; however, the conventional
brake can be operated.
The brake actuator temperature increases
during continuous operation of the follow-
ing systems under conditions such as on
slippery roads.

too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the downhill assist
control system can no longer operate. In
this case, stop your vehicle immediately at
a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
At this time, the slip indicator light will
come on and the downhill assist control
system stops operating temporarily in or-
der to protect the brake actuator. (Al-
though the downhill assist control system
does not operate, it is no problem to con-
tinue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.
